a lot of people unintentionally apply intentionality to evolution.
also, just because we are capable of recognizing a more efficient development cycle or design of any given 'naturally' occurring life form does not mean that the efficient conception should have occurred. that's like saying that because we can watch mike tyson lose his edge we can say that it makes no sense that he still boxes. can he still stand? can he still swing his arms? when he swings his arms do people still get knocked out? if so, he has some survivability as a boxer. if not, he does not, and will fail as a boxer. things don't simply instantly disappear when it has been revealed that their methods aren't totally efficient.
